outcomes of ablation of unresectable pancreatic cancer using the nanoknife irreversible electroporation system-

Conditions: Pancreatic Cancer Non-resectable

Summary: the purpose of this study is to evaluate the short and intermediate term safety of the nanoknife irreversible electroporation system when used off-label to treat unresectable pancreatic cancer. in addition, the study will evaluate the efficacy of this device in treating pain associated with unresectable pancreatic cancer. quality of life post-procedure will also be collected.

the nanoknife, system has been commercially available since 2009, and is fda-approved to treat soft tissue tumors. the nanoknife system has received fda clearance for the surgical ablation of soft tissue. it has not received clearance for the therapy or treatment of any specific disease or condition. the purpose of this study is to evaluate the short and intermediate term safety of the nanoknife irreversible electroporation system when used off-label to treat unresectable pancreatic cancer. in addition, the study will evaluate the efficacy of this device in treating pain associated with unresectable pancreatic cancer. quality of life post-procedure will also be collected. primary objective: • safety and tolerability of the procedure by monitoring the number of participants with adverse events at the following time points: 1, 2, 4, 7, 14, 21 and 30 days and 3, 6, 9, 12, 15, 18, 21, and 24 months post-ire procedure. secondary objective: • pain and quality of life outcomes of the patient using pain scores on the visual analogue score (vas) and quality of life scores on the eortc qlq-pan26 and eortc qlq-c30 at the following time points: 1, 2, 4, 7, 14, 21 and 30 days and 3, 6, 9, 12, 15, 18, 21, and 24 months.
